[0041] It should also be noted that the exhaust pipe of the air-conditioning compressor is not too heavy, and this set of structures can smoothly drive the pipe to rotate.

[0042] For details, please refer to the attached Figure 2 The welding table 10 is composed of a fixed table 11, a movable table 12 and a fixed plate 13.
